Answer:
Hydrogen is usually classified as a group 1 element since it has one valence electron, just like group 1 metals.
Explanation:
Answer:
Mg
Explanation:
Mg requires more ionization energy to ionize because it has more protons than Na. If an atom, located within the same period, has more protons, the pull on the electrons will be greater. This makes it more difficult to remove these electrons during ionization.
As a general rule, ionization energy decreases as you go down a column and increases as you move to the right on the periodic table. Therefore, the elements with the highest ionization energies are located on the top right of the periodic table. Ionization energies increase across a group due to the quantity of protons increasing. Ionization energies decrease as you go down a column because the outermost electrons are further from the nucleus (where the protons are), making it easier to remove them.
<span>Phosphate ester bonds exist in adenosine and phosphoanhydride bonds are found in ATP. I think for every two A's, you have 1 phosphate ester bond. Since there are 3 P's in ATP and I think there would only be 2 phosphoanhydride bonds. Hope this answers the question.</span>
<u>Answer:</u> The amount of oxygen gas consumed is 0.525 moles
<u>Explanation:</u>
We are given:
Moles of propane burned = 0.150 moles
The chemical equation for the combustion of propane follows:
By Stoichiometry of the reaction:
1 mole of propane reacts with 5 moles of oxygen gas
So, 0.150 moles of propane will react with = of oxygen gas
Hence, the amount of oxygen gas consumed is 0.525 moles
